## the short version

personal.ai wants to build a copy of you. innernet doesn't want to be you — it wants every AI you already use to know you.

That sounds like a small difference in ambition. It's the largest difference in this whole set of comparisons, because it determines where the memory ends up. A twin needs the memory inside itself to work. A layer needs the memory outside everything to work.

personal.ai has been building toward the personal AI thesis since before the category had a name, and deserves credit for it. We just think the twin is the wrong destination for personal memory.

## what personal.ai is building

*"Make Your Own AI with Your Unique Memory"* — an AI Memory Platform that *"remembers, connects, and evolves."* Three concepts carry it: a **Memory Stack**, secure stores of preferences, requests, dates and facts that link into a personal knowledge base; a **Personal Language Model** trained on what you feed it, where output quality is explicitly a function of memory quality; and an **AI Twin** that learns your preferences, communication style and habits and can act as a consultant — or answer on your behalf.

Inputs come from documents, URLs, social accounts and voice. Hashtag labelling organises the stack. Web plus mobile.

## what innernet is building

A memory layer that sits under the AI tools you already use. One command — `npx innernet` — connects Claude Code, Cursor, Codex, Windsurf, Gemini CLI, Claude Desktop, VS Code, Cline, Zed and Continue to the same memory, with an MCP endpoint for everything else. netti, one per person, files what accumulates into Context Maps — dimensions, nodes, commits, branches — and every fact carries how far it may travel.

We are deliberately not a model, not a twin and not a chat product. The memory has to outlive all three.

## where they diverge

### 1. delegation vs. continuity

A twin's value proposition is that it can stand in for you — answer, advise, represent. innernet's is that you never have to explain yourself twice to a tool you're using yourself. One is about being replaced in a conversation. The other is about being understood in your own work. If you want the first, personal.ai is aimed at it and we are not.

### 2. a model trained on you is a container you can't leave

The Personal Language Model is the strength and the trap. Memory expressed as model weights, or as a stack that only that model reads, is memory bound to that model's lifespan and that company's roadmap. innernet holds memory as readable structure and refuses to own a model at all — which is the only reason "neutral layer" is a fact about us rather than a claim we have to defend.

### 3. what you tell it vs. what accumulates

A twin is fed: you upload documents, connect accounts, dictate memories, tag them. That produces a self-portrait — accurate about what you chose to say. innernet reads what actually accumulates as you work, and netti writes conclusions from it, including ones you wouldn't have thought to state. The interesting facts about a person are rarely the ones they sit down to record.

## side by side

| | personal.ai | innernet |
|---|---|---|
| The goal | an AI twin that can answer as you | every AI you use understanding you |
| Where memory lives | inside the Memory Stack, read by their model | outside every tool, read by all of them |
| Model posture | trains a personal language model | owns none, resells none, ever |
| How it's fed | uploads, URLs, social, voice, hashtags | what accumulates in your actual work |
| Structure | memory stack, hashtag labels | dimensions and nodes netti designs per project |
| Change over time | memory updates | versioned; earlier positions kept as phases |
| Works inside Claude Code / Cursor | not the surface it's built for | yes, in one command |

## where personal.ai is genuinely better

- **Conviction and head start.** They committed to personal AI years before it was fashionable, and the Memory Stack is a serious attempt at the hard part.
- **The twin is a real product.** If you want something that can respond on your behalf, that's a coherent thing to want and they build it.
- **Input breadth.** Documents, URLs, social accounts and voice give people an easy on-ramp.
- **Delegation is a genuine use case.** For someone answering the same questions all day, a twin has obvious leverage.

## where innernet is stronger

- **The memory isn't trapped in a model.** It's readable structure, connected by URL, and it survives any model's deprecation — including ones we'd have picked wrong.
- **It works in the tools you already have.** No migration of your working life into a new app.
- **Per-fact disclosure.** Every fact carries how far it may travel, enforced when a tool reads. Private and self-only facts never leave your Self Map.
- **Contradiction is kept, not smoothed.** A twin has to present a coherent you. A memory doesn't — and shouldn't, because the incoherence is where the person is.

## which one you want

**Use personal.ai if** you want an AI that can represent you — answer questions in your voice, hold your expertise, act as a stand-in.

**Use innernet if** you want the AI tools you already use to stop asking you to explain your own project, and you want that to keep working when you change tools, models or minds.

## the question we actually get

> "A personal language model trained on me has to know me better than a memory file, surely?"

It knows you more *fluently* — it can imitate your voice, which a structured memory can't. But fluency isn't knowledge. A model trained on your material will produce confident sentences about you whether or not the underlying fact is still true, and it has no way to show you which position it's speaking from or when you changed it. innernet gives you the fact, its sources, and the version you held before. Less impressive in a demo. More useful when you need to trust it.
